Rutherford (1871–1937) was responsible for a remarkable<span> series of discoveries in the physics, especially in the atomic model.
</span>He identified the atomic nuclei - a relatively high central charge concentrated into a very small volume in comparison to the rest of the atom.
The Rutherford model is a model of the atom we know today.
I think it would be “use reasoning statements to show how the data supports your claim”
KE=1/2 mv²
= 1/2 × 70 × (6)²
= 1260
<span>There are several factors that can influence sonic booms - weight, size, and shape of the aircraft or vehicle, plus its altitude, attitude and flight path, and weather or atmospheric conditions.</span>
Answer:
368224.29906 m/s
Explanation:
M = Mass of Polonium nucleus = 214 u
V = Velocity of nucleus
m = Mass of Helium nucleus = 4 u
v = Velocity of alpha particle = 
In this system the momentum is conserved
The recoil speed of the nucleus that remains after the decay is 368224.29906 m/s
